Need help with a Coop ASAP... Saving lives of hens

Does anyone have a coop for sale, trade or free? How about pieces of a coop or wiring?
I am attempting to save a flock of birds that were being neglected. My neighbor has agreed to let me use his yard to raise these chickens. My flock is not happy with being combined with them. I would greatly appreciate any help I could get.

Keep in mind that coop manufacturers grossly exaggerate the number of birds their buildings will accommodate.
I'm not familiar with that manufacturer but, 10 chickens need 40 square feet of floor space. Multiply the interior width by length. If it doesn't come out to 40 sq. ft. or more, they're less than truthful.
